Coming from U2.com's BajaGirl:
"At this time, the official word on how the floor procedure will work HAS NOT BEEN MADE. The concert promoter and Management have to speak to the local venue, and follow security protocols and ALL local/state ordinances, before determining the procedure. Then it has to be approved by the Fire Marshall of the locality, so don't expect an announcement until we are much closer to the show dates, as it could vary by location. Please check back before your show.
As soon as I am told the procedure, I shall post the information.
In other news:
Signatures network has added [at the request of U2.com] more resources [techs] in order to handle subscribers with problems. I have been requested to direct you to the CONTACT US form on the HELP PAGE (<= link) and to use the form to report access, login, presale code, webmail, not receiving emails and any other technical or customer service difficulty you might be experiencing"
As EdgeFest has been saying, don't ask about the GAs -_-
